Look at half of the journey men in the heavyweight division. They are in a amazing shape. Also guys like Travis Walker, Rafael Butler ect
Arreola, Chambers, Povetkin, Estrada, Toney, Williams, Gomez, Lyakhovich, Brewster, Johnson, Solis, Tua.......
word "talented" doesn't apply to all of them. except maybe Povetkin and Solis. and Toney's shot to hell, but he used to be in good shape back in the days.
In general I think it's the American & Latin American Heavyweights you're talking about. Joe Mesi, Chris Arreola, James Toney, Solis, etc. Most of the European & Former Soviet Heavys are in decent to Excellent shape. The Klitschkos, Haye, Dimentrenko, Virchis, Krasniqi, Skelton, and to a lesser extent Chagaev, Valuev & Ibragimov. These last 3 aren't "cut" or slim & trim but they aren't fat slobs either. When Arreola takes a punch his tits jiggle.....................
